The DHT22 sensor (like the DHT11) has four pins. I place the DHT22 sensor on the breadboard with the front facing
In this Arduino Tutorial we will learn how to use the DHT11 or the DHT22 sensor for measuring I also made an example where I display the results on a LCD.
To use the DHT22 and the LCD we need the libraries “DHT.h” and “LiquidCrystal.h”. In “LiquidCrystal.h” it is necessary to define the Arduino pins to the LCD will
In this tutorial you will learn about interfacing the temperature and humidity sensor DHT22 with arduino and displaying the result on the LCD.
However, the LCD Display library is inbuilt within the Arduino IDE. delay(1000); // Reading temperature or humidity takes about 250 milliseconds! float h = dht.

14 Nov 2017 Arduino with DHT22 (AM2302, RHT03) humidity and temperature sensor. Results are displayed on 1602 LCD. With circuit, Arduino code and
25 Mar 2018 Hello everyone,. In this tutorial we’ll try to measure temperature and humidity using the DHT22, DHT22 and DHT11 are famous sensors used aLiquidCrystal_I2C lcd(0x27,16,2); // set the LCD address to 0x27 for a 16 chars and 2 line display. //Constants. #define DHTPIN 2 // what pin we’re connected to.
